Released on February 26th, Hyperledger Besu v1.4 offers numerous anticipated features, including End-to-End TLS support for incoming and outgoing RPC endpoints.

Why Do We Care About TLS?

The adoption of Enterprise Ethereum across industries and organisations continues to accelerate as more projects move from inception to deployment. As implementers assess the suitability of the solution for their edge cases and threat models, and as system integrators battle the multitudes of business layer applications that need to interconnect, the need for in-depth security becomes more apparent. Ensuring the safety and security of data is everyone’s responsibility, and a key requirement for projects moving to production-ready status. PegaSys is here to provide you with a secure, robust and tamper-proof end-to-end solution that you can take into production.

What Does End-to-End Really Mean?

We know that the core blockchain technology provided by Hyperledger Besu is secure, but what about when data leaves the edges of the blockchain network through ancillary systems and applications? What happens when your blockchain transaction is being crafted and produced and transferred to your Besu node in the network?
